javascript - AngularJS Select element set the selected index -

so i'm using angular , select html:

<select id="date" ng-model="selectedday" ng-change="setdate()" > <option>another option</option> <option>an option</option> </select>

this in controller:

$scope.selectedday; document.getelementbyid("date").selectedindex = "0";

the result: 3 options: 1 blank (which default selected) , 2 options made in html

what hell? why isn't default when open view "another option"

firstly, check official documentation. angularjs documented.

secondly, not utilize document.getelementbyid ("date") selectedindex = "0" - that's javascript. avoid using pure javascript when angular function available.

javascript html angularjs default selectedindex
